The purpose of this study is to investigate the impacts of two different kinds of interactivity, such as user-to-user and user-to-media interaction, on the relationship between SNS motivation and online word of mouth (WOM). An online survey was conducted with SNS users in Korea. Using the convenience-sampling method, 300 surveys were collected and 295 were used in the actual analysis after excluding data with careless responses or missing values. Hypotheses were tested using Structure Equation Model (SEM) and path analysis by using AMOS22. The results indicate that four different SNS motivations (self-expression, relational, fun, and browsing motivation) have a partially significant positive effect on perceived user-to-user and user-to-media interaction in SNS. Although both user-to-user interactivity and user-to-media interactivity were found to have a significant effect on online word of mouth, by comparing the standardized regression coefficients in these relationships, it was found that user-to-user interactivity has a greater effect on online WOM than user-to-media interactivity. These results show that the motivated SNS users want to express their desire to communicate with other users in contrast than their desire to learn media functions when motivated SNS users reveal their personalities, knowledge, and abilities. Theoretical and managerial implications are discussed.

차세대 이동통신 시스템에서는 새로운 주파수 대역에서 다중 안테나 사용이 높은 데이터 전송률과 용량을 가능하도록 만들 것이다. 본 논문에서는 국내 전파 특성 측정을 통해 도출된 채널 파라미터(경로 손실, 지연 확산, 각 확산, K-factor) 간에 상관도를 분석하였다. 측정은 DTV 방송과 혼신을 피하기 위하여 제주도에서 채널 사운더와 $4{\times}4$ 안테나로 측정하였다. 채널 파라미터 간에 상관도 분석은 유사한 환경에서 통신 시스템을 설계하는데 있어서 많은 도움을 줄 것이다.

본 연구는 디지털 콘텐츠의 불법복제와 관련하여 이에 영향을 미치는 다양한 요인을 분석하고자 이러한 행위가 비교적 빈번하게 발생한다고 판단되는 대학 현장에서의 불법행위에 초점을 두고 사용자의 윤리적 성향과의 상관관계를 분석하였다. 합리적 행동이론을 토대로 디지털 콘텐츠 불법복제의도, 태도, 주관적 규범, 불법복제 적발시 예상되는 처벌의 심각성 등의 연구요인을 도입하고 설문조사를 통해 연구모형의 타당성을 검증하였다. 295개 설문자료를 이용하여 가설 검증을 시도한 결과, 처벌의 심각성은 주관적 규범과 태도에 영향을 미치며, 이 두 요인은 디지털 콘텐츠 불법복제의도에 유의한 영향을 미치는 것으로 나타났다. 또한 윤리인식 설문이론을 토대로 하는 상대주의 개념을 조절변수로 설정하여 연구모형을 구성하는 계수간의 차이를 분석하고 시사점도 함께 논의하였다.

Purpose: The purpose of this study was to identify the mediating effect of professionalism in the relationship between clinical competence and field adaptation in newly graduated nurses. Methods: The participants in this study were 213 nurses from four tertiary hospitals who had less than 12 months of nursing experience. Data were collected during January and February, 2013. A structured questionnaire was used for data collection and data were analyzed using descriptive statistics, Pearson correlation coefficients, and path analysis with the SPSS/WIN 21.0 and AMOS 21.0 programs. Results: The mean score for clinical competence was $2.85{\pm}0.25$, for professionalism, $3.10{\pm}0.30$, and for field adaptation, $2.79{\pm}0.37$. There was a significant positive relationship between clinical competence and field adaptation. Also, professionalism was positively correlated with field adaptation. Professionalism showed mediating effects between clinical competence and field adaptation. Improvement of clinical competence increased professionalism and the increased professionalism raised the field adaptation. Conclusion: Based on these findings, orientation programs including strategies to increase professionalism, should be established to promote effective field adaptation in newly graduated nurses. These orientation programs can strengthen professionalism, the mediator between clinical competence and field adaptation in newly graduated nurses.

This paper presents experimental result of characteristics about Closed circuit Cooling Tower having a rated 2RT. The experimental apparatus has been set-up with a conventional type system. The test section is heat exchangers of cooling tower that consist of different vertical tubes, 15.88mm with 10 rows and columns and 19.05 mm with 8 rows and 12 columns. The main results were summarized as follows : The values of heat and mass transfer coefficients of cooling tower operating with two paths are higher than these with one path. Cooling capacity per unit volume using 15.88mm tubes are higher than 19.05mm tubes.

This study investigated the relations between gratitude disposition and the ego-integrity of elderly men and women, focused on generativity and relatedness toward spouse, children, and friends as well as examined gender differences for each path. The subjects were 341 Korean elderly men and women over the age of 60 living in the Busan, Daegu, and Gyeongsang areas. Collected data were analyzed by PASW ver. 18.0 and AMOS 20.0 programs; in addition, frequency, Cronbach ${\alpha}$, Pearson's correlation coefficients, t-test and structural equation modeling were also used for data analysis. The results were as follows. First, the Korean elderly's gratitude disposition had a positive influence on ego-integrity and generativity as well as on relatedness toward spouse, children, and friends. In addition, the relatedness toward spouse, children, and friends of Korean elderly had direct influences on generativity and indirect influences on ego-integrity by mediating generativity. Second, it showed that there was a gender difference in the structural model that explained the relations among the variables. Korean elderly men's relatedness toward spouse, children, and friends had direct effects on generativity. However, in case of Korean elderly women, only relatedness toward children and friends had effects on generativity. The results were discussed in terms of elderly education.

Constructs with seven latent evaluation indicators and 18 observable survey questions were developed by food and nutrition experts to calculate a food safety recognition and practice index for children. The purpose of this study was to suggest statistical approaches to test construction validity on the constructs, obtain weights of the evaluation indicators, and develop questionnaires to calculate a children's food recognition and practice index. Survey data of 2,400 elementary fifth grade students were used as empirical results. Test validity was evaluated by exploratory factor analysis and confirmed to be highly significant by confirmatory factor analysis [i.e., linear structural relations (LISREL) analysis]. Standardized path coefficients of the LISREL analysis were suggested based on weights, and the weights were compared using the AHP and Delphi methods.

The study seeks to identify the determinants of the adoption of e-commerce by small and medium-sized enterprises (SMEs) in developing countries, in our case, in Indonesia. The aim of this study is to examine the factors influencing e-commerce adoption. This study uses the method of quantitative data collection based on a questionnaire survey of SMEs in Indonesia. The research relies on Regional Project stipulations regarding Business Development in Indonesia, to capture businesses with a range of 5 to 100 employees that are classified as SMEs. This study randomly chose 100 SMEs in Indonesia from the IndoNetwork database. Partial least square (PLS) structural model data processing was used for path coefficients analysis. Structural equation modeling is applied in this study to analyze the determinant factors on the e-commerce adoption. The study findings reveal that four factors, namely, perceived benefits, compatibility, technology readiness, and government support, significantly influence the adoption of e-commerce, whereas customer/supplier pressure does not have influence. So, this study concludes that perceived benefits, compatibility, technology readiness, and government support had a significant and positive relationship with e-commerce adoption. Meanwhile, customer/supplier pressure had no effect on the e-commerce adoption of by Indonesia SMEs.

Gamma radiation shielding features for three series of binary alloys identified as (Pb-Sn), (Pb-Zn), and (Zn-Sn) have been investigated. The mass attenuation coefficients (µ/ρ) for the selected alloys were simulated using the MCNP-5 code in the energy range between 0.01 and 15 MeV. Moreover, the (µ/ρ) values were computed using WinXCOM database in the same energy range to validate the simulation results. Results reveal a good agreement between the simulated and computed values. The half value layer (HVL), mean free path (MFP), effective atomic number (Z_eff) and exposure buildup factor (EBF) were evaluated for the selected binary alloys. Results showed that the PS1, PZ1, and ZS2 alloys have the best shielding parameters and better than the commercially standard and available radiation shielding materials. Therefore, the investigated alloys can be used as effective radiation shielding materials against gamma ray with energies between 0.01 and 15 MeV.
